Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

Simultaneous Electrochemical Detection of NGF and proNGF Under Native Conditions Using Molecularly Imprinted Polymers: Toward Point‐of‐Care Diagnosis of Alzheimer's Disease

Advanced Healthcare Materials, Volume 15, Issue 23, 19 June 2026.
This study relies on the development of a new sensor that can detect two closely related proteins involved in Alzheimer's disease at the same time. Unlike traditional methods, it works in natural conditions and does not require sample pretreatment. The device is highly sensitive and was successfully tested on patient samples, offering promises for ...

Thinner silicon-based tandem solar cell with high efficiency made by hot wire CVD

, 2011
We developed thin film silicon tandem cells with hot-wire deposited amorphous (protocrystalline) and nanocrystalline i-layers, with a total thickness of only 1.43 µm. This is considerably thinner than the thickness of 2.5–3.0 µm normally needed, which is

A Colloidal Quantum Dot Thermistor and Bolometer

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Morphology‐Controlled Silica Nanoparticle Coatings for Transparent Radiative Cooling

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Transparent radiative cooling coatings are achieved by immobilizing solid and hollow silica spheres on glass. Particle morphology within sub‐monolayer coatings is shown to govern the trade‐off between visible and atmospheric window reflectance. Hollow‐sphere structures enable reduced thermal emission losses while preserving transparency, highlighting ...
